This standard specifies a basic application interface that augment the DSRC protocol functions to allow executing non-IP type multiple applications of different types and with different functionality in the communication between a Land Mobile Station and Base Station in a DSRC system as defined by the ARIB STD-T75 "DEDICATED SHORT-RANGE COMMUNICATION (DSRC) SYSTEM" and ARIB STD-T88 "DEDICATED SHORT-RANGE COMMUNICATION (DSRC) APPLICATION SUB-LAYER" standards.

The DSRC system covered by this standard consists of a Base Station and Land Mobile Station and equipment for testing. The standard specifies the following six types of basic application interfaces for roadside-to-vehicle communication within such a DSRC system.

(1) OBE instruction response application

(2) OBE memory access application

(3) IC card access application

(4) Push-type information delivery application

(5) OBE ID communication application

(6) OBE basic indication application
